Dear all,
We are working with 13C CPMAS NMR of mixtures of crystalline organic
materials.
For quantitative purposes, to get a better determination of the ratio of two
different materials, I would be interested in improving the resolution of
the spectra in a certain region or to get sharper peaks less overlapping or
to shift them to get a better separation....
As we have already tried all the basic and classical tricks we know, my
question is probably stupid but I leave it opened : are there any
possibilities to do that without changing the equipment (i.e. special
sequences, special recording; special processing, solid state shift reagents
(?) etc... etc...).
Any idea ?
Thanks for your help
Francois
